 is the most popular piggyback tuning device in Europe. Despite its small size, the DET3 is an extremely capable piggyback tuning device. The DET3 allows for the removal of the airflow meter on most applications, and ignition timing can be monitored and adjusted via 16x16 tables. The parametric output channels can be configured to control  boost with the use of a boost control solenoid, nitrous activation, water or methanol injection control, etc. Launch control and map switching are also among the advanced features available to the end user. In "Fuel Implant" mode, the DET3 operates much like a standalone ECU, calculating fuel requirements based on RPM, IAT, CLT, TPS and even O2 feedback, and can drive up to 4 injectors directly (in normal installations the injectors are not controlled directly, so the DET3 can be used with any number of injectors, you are not limited to 4). The DET3 is a comprehensive piggyback device and is equipped with a 4 bar MAP sensor.
